Processing details
• These instructions decode the data consisting of 0 to F specified by the lower 4 bits in the device specified by (s) to seven-
segment display data, and store the decoded data in the device specified by (d).
• In the case of a bit device, (d) indicates the start device for storing 7-segment display data. In the case of a word device, it
indicates the device number for storing the data.
Ex.
Bit device
